WATERrCLOSET.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed June 30, 1910. Serial No. 569,802.

To all whom it may concern: Be it known that I, IRA A. MANN, a pitizen of the United States, residing at PltllS I burgh, in thecounty of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Water-Closets, of which the following is a specification.

The invention relates to water closets and particularly to what are known as wall closets, that is closets hung or supported from the wall as opposed to those in which the support is from the floor. The invention has for its primary objects, the provision of a Wall closet in which the distance the bowl projects from the wall is reduced to a minimum; the provision of a wall closet in which the siphon is entirely inclosed in the bowl structure in a novel and compact manner permitting the center line of the bowl to be placed close to the wall upon which it is supported; and the provision of improved means for rigidly supporting the bowl without injury I to the wall or to the bowl. Certain embodiments of the invention are illustrated in the accompanying drawings wherein Figure 1 is a side elevation, partially in section, of the improved closet as applied a wall.

Figure 2 is a partial plan view and section taken just above the closet.

Figure 3 is a rear view of the closet removed from the wall.

Figures 4 and 5 are a plan view and side elevation, of the bowl removed from the wall the elevation in Fig. 5 being taken from the opposite side from that shown in Fig. 1.

' Figure 6 is a plan view of the bearing plate employed behind the wall or partition.

Figures 7' and 8" show a modified bowl structure.

Fig. 9 shows still another form of bowl structure.

Figures 7, 8 and 9 are enlarged detailed views showing the im roved joint construction. Figure 7 being a section through the joint member in the bowl; Figure 8 being an end view of the joint member of Fig. 7 and igure 9 being a side view of the coupling member for engaging the joint member shown in Fig. 7.

Figures 10 and 11 are sectional and end view respectively of the tool employed for positioning the coupling shown in Fig. 9.

Figures 12 and 13 are enlarged detailed view of a modified form of joint member and coupling which may be employed, F igure 12 being a sectioni through the joint member and Fig. 13 being a side view of the coupling member employed therewith,

and

Figures 14 and 15 are sectional and end views respectively of the tool to be employed in positioning the coupling of the Fig. 13.

Referring to the general arrangement as shown in Figures 1 and 2 the principal parts may be enumerated as follows. 1 is the bowl of the closet having at its rear side the plate or shelf 2 bearing against the supporting wall or partition 3; 4 is a metal bearing plate placed behind the wall or partition 3 and secured to the shelf 2 by means of the bolts 5; 6 is the outlet or soil pipe provided with the vent pipe 7 to which the bearing plate 4. is secured by means of the loop 8; 9 is a metal joint member secured in the bowl; 10 is a coupling for connecting the joint member 9 to the soil pipe 6; 11 and 12 are the seat and cover respectively. which members are pivoted to the fixtures 13 and 14 carried by the bolts 55 in the manner indicated in Figs. 1 and 2-; and 15 and 16 are cross members carried by the framing of the partitional wall to which cross members the metal bearing plate 4 is secured.

One of the important features of my invention consists in the arrangement of the siphon passage whereby the space in the bowl to the rear thereof occupied by the passage is reduced and the bowl placed nearer to the wall than would be the case if the siphon passage were otherwise arranged. The siphon passage is indicated in dotted lines in Figs. 1, 3, 4 and 5, and by reference? to these figures it will be noted that thefoutlet 17 from the bowl to the siphon passage extends laterally instead of to the rear as in the ordinary form of bowl construction. From the outlet 17 the passage extends upwardly and rearwardly as indicated at 18 in Fig. 1, thence curves laterally as indicated at 19, thence curves downwardly as indicated at 20 and finally curves to the rear as indicated at 21. It

will be seen that by this arrangement it is necessary to provide space between the bowl orifice and the wall for one diameter of the siphon passage only, whereas if the ordinary siphon arrangement were employed extending straight back from. the outlet instead of sidewise, it would be necessary to provide space for two diameters of the siphon passage, ind the bend at the upper end of the siphon would either occupy considerable space, or would have to be bent so short as to reduce the flow of the Water therethrough. By the arrangement shown contracted bends are entirely avoided, thus insuring a free flow of water through the passage, and the lateral enlargements in the bowl structure incident to the use of the side outlet are so slight and in such position that the appearance of the bowl is not seriously affected. The siphon jet passage-is indicated at 22, such siphon jet passage having its outlet at 23.

The provision of the bearing plate 4 is important as such plate serves to give a very firm support for the bowl, which support would not ordinarily be afforded by the ordinary wall or partition. The bolts 5 serve to support the plate or shelf 2 and at the same time form the securing means for the seat fixtures or brackets 13 and 14. The bearing plate is forked to surround the outlet pipe 10 as indicated in Fig; 6, and its extreme ends are turned back as indicated at 24 and 25 (Figs. 1 and 6) in order that the plate may be more securely supported upon the transverse beams 15 and 16, which beams are ordinarily supported on the usual timber uprights 26. A number of holes 27 are provlded through the plate 4 to receive screws or other securing means, the plate being preferably secured to the beams 15 and 16- y means of screws. A very rigid support for the bearing plate is thus provided. and this support is still further increased by means of the strap or loop 8 passing around the vent pipe 7 and secured to the plate 4 at its ends. As indicated in Fig. 3 the holes 28 in the shelf 2 for receiving the bolts 5 are somewhat'elongated in order to permit of a vertical adjustment of the bowl and to permil; the bowl to move vertically a slight amount to adjust itself to the expansion of the soil pipe 6 to which the bowl is rigidly secured. The invention, in so far as the means for supporting the bowl from the piping are concerned, is applicable to other types of bowls used in plumbing aside from closet bowls.

The joint construction which is preferably used is shown in detail in Figs. 7, 8 and 9. A joint member 9 having inclined recesses 30 and a tapered ground surface 31 is secured in the bowl by means of the lead or other packing 32, and this member is adapted to be engaged by the coupling memco6perating with the surface 31.

ber 10, whichmember 10 is provided with lugs 32 for cooperating with the recesses 30 and with the ground tapered surface 33 for The other end of the member 10 is provided with the usual tapered pipe thread 34 for engaging the thread upon the interior of the pipe 6. The tool employed for screwing the coupling 10 into the pipe 6 is shown in Figs. 10 and 11. This tool is provided with a wrench engaging portion 35 and has upon its inner surface a tapered portion 36 and inclined lug engaging recesses 37, which surface and recesses are exact duplicates of those upon the joint member 9. This member will therefore screw upon the outer end of the member 10 and the portion '34 can then be screwed into the pipe 6 until it is tight. If, when screwed in tlght, the lugs 32 do not occupy their proper rotative positions or if they are too far out from the wall, the member 10 is removed and a member of slightly different length is substituted or else the screw thread upon the interior of the pipe is cut a trifle farther, and this member is then screwed into the pipe 6. This method of adjustment is pursued until the lugs 32 upon the end of the member 1 0 occupy exactly the proper position rotatively and longitudinally when the other end of the coupling is screwed tightly into the pipe 6. The accuracy of the position of the outer end of th member 10 can be readily gaged from the tool employed in screwing the coupling into position, as the flange 38 is' so positioned that it will engage the wall when the coupling is properly positioned, and this flange is also provlded with a mark 39 (Fig. 11) which serves to indicate the proper rotative position of the lugs 32. After the coupling 10 is thus properly positioned the bowl 1 is placed so that the joint member 9 fits over the outer end of the coupling 10 and is given a movement to upright position, which movement causes the lugs 32 to engage the recesses 30 and draw the tapered surface 33 tightly against the surface 31.

In Figs. 12 and 13 a modified form of joint member 9 and coupling member 10 are shown, such connecting means difiering from that shown in Figs. 7, 8 and 9 in that an ordinary thread is provided between the interior of the joint member and the coupling member instead of the quick thread connection. This form of connection, of course, requires that the bowl be rotated a number of times in order to screw it to position, and the connection cannot therefore be used in those cases in which the outlet is as close to the floor as that shown in Fig. 1, as the bowl cannot in this construction make a full revolution. This form of connection can be very cheaply made, and the coupling member 10' is adjusted by means of a tool 39' which screws onto the end of the conpling member, the method of adjustment being substantially the same as that heretofore described with relation to the device shown in Figs. 7. 8 and 9.

In i l 7 and S a modified form of bowl structure is shown, the arrangement of the siphon passage being somewhat different from that shown in Figs. 1 to In this arrangement the short leg 40 lies more directly at the side of the bowl and is provided at its upper end with the recurved portion 41 for improving the draw. point the passage curves laterally to the center of the bowl as indicated at 42 and then to the rear as indicated at 43.

In Fig. 9 still another form of bowl is shown in front elevation, both legs of the siphon 44 and 45 lying to the front of the bowl orifice with the substantially horizontal portion 46 extending backwardly under the orifice of the bowl to the outlet in the rear side of the bowl structure.
